UNITED STATES PATENT OFFICE,

THOMAS H. WHITE, OF ORANGE, MASSACHUSETTS.

IMPROVED KNIFE-SHARPENER.

Specification forming part of Letters Patent No. 57,804, dated September4, 1866.

To all 'whom t may concern;

Bc it known that I, THOMAS H. WHITE, of Orange, in the county ofFranklin, in the State of Massachusetts, have invented a new andImproved Knife-Sharpener; and I do hereby declare that the following isa full and exact description thereof, reference heilig had to the accompanying` drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the combination of circularcutters with each other and with an ordinary hone or sharpening-strop,the whole forming a convenient and simple apparatus for sharpeningknives.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and use.

In the drawings, Figure l is a view of the front of my knife-sharpener.Fig. 2 is a view of the back of my knife-Sharpener. Fig. 3 is a view ofone side of my knife-Sharpener.

The handle or stock A may be of wood or any other suitable materialworked into thc proper form and size. Upon the stock A are screwed twocircular disks, B B', of steel, the peripheries of which are beveled, asshown. These cutter-wheels are arranged upon the Vsame plane, and sothat their peripheries are nearly or quite in contact.

' The disks are made with diamond or beveled edges, and are very hard,so that when a knife is drawn between them they take a shaving from eachside of it as often as the operation is repeated, and thus the edge ofthe knife becomes thin and sharp; but this operation produces a roughsaw-like edge, and it will be necessary to use the other part of myinstrument in order to make a smooth edge.

That part of my instrument which I use for iinishing the edge is shownin Figs. 2 and 3,

and consists of a hone or strop, O, which may be made of any fine stone,or of a piece of nice thick leather. Its use is obvious.

The advantages that I claim for my knifesharpener are that it is cheap,simple, and has the necessary parts for forming a complete smoothcutting-edge.

that I claim as my invention, and desire to secure b v Letters Patent,is-

The arrangement and combination of the circular disks B B with the stockA and the strop or hone C, substantially as described, and for thepurpose set forth.

THOMAS H. WHITE.
